Not all chargers are born equal, especially when it comes to Qi2.2 compatible units. Achieving 25W wireless charging requires more than just a slab with a coil. This week Lee checks out the ESR CryoBoost Foldable 3 in 1 – 25W Charger.
It is compatible with iPhone 12 series and later, except for SE, Mini series and 16e) and will work through a MagSafe case of up to 2mm thickness.
Additionally you can charge your Apple Watch and AirPod at the same time.
As the name suggests, the ESR has active cooling technology built into the charger, a necessity to achieve the peak charge rate.
When not needed, it can even fold down for easy storage, whether it stays on your desk or for travelling.
So without much ado, take it away Lee.
The ESR CryoBoost Foldable 3-in-1 comes with a US plug, with a RRP A$157.23 on Amazon although there is 10% discount at time of publishing bringing it down to A$141.65. It is also available on their website in black and a frosted graphite version.
DRN would like to thank ESR for providing the review unit.
